(PEMDAS): Parentheses, Exponents, Multiplication, Division, Addition, Subtraction -
answer-Order of Operations
• Compare two quantities (e.g., 2:3 or 2/3 ).
• Example: If a recipe calls for 2 cups of flour and 3 cups of sugar, the ratio is 2:3. -
answer-Ratios
(Conversions) Divide by 100 ( 75% = 0.75 ). - answer-Percent to decimal
(Conversions) Multiply by 100 ( 0.4 = 40% ). - answer-Decimal to percent
• Part = Percent × Whole.
• Example: What is 20% of 50? 0.20 x 50 = 10 . - answer-Finding percentages
• Percent Increase: new - old/old X 100%
• Example: Price increases from $50 to $60: 60 - 50/50 x 100 % = 20% - answer-
Increase/decrease
• Combine like terms: 3x + 5x = 8x . - answer-Simplifying Expressions
• Isolate the variable:
3x + 4 = 10 -> 3x = 6 -> x = 2 . - answer-Solving Equations
